Abstract

U ovom diplomskom radu obrađena je MPLS (engl. Multiprotocol Label Switching)
tehnologija, koja danas igra ključnu ulogu u prijenosu paketa kroz mrežu. MPLS predstavlja
nadogradnju tradicionalnog prijenosa paketa, čineći detaljnu analizu svakog paketa od strane
usmjerivača nepotrebnom. Umjesto toga, koristi se metoda komutiranja oznaka, pri čemu se
usmjeravanje paketa pojednostavljuje dodavanjem oznaka. Ova tehnologija omogućava
značajna poboljšanja u kvaliteti usluge, uključujući visoku dostupnost, nisku latenciju i
minimalan gubitak paketa. Diplomski rad detaljno opisuje značajke, razvoj i arhitekturu MPLS
mreža, protokole korištene za prijenos podataka te osnovne dijelove mreže, kao i proces
definiranja kontrole protoka paketa te prosljeđivanja paketa prema klasi. U istraživačkom
dijelu rada provedena su mjerenja i analiza ključnih pokazatelja kvalitete usluga, kao što su
propusnost, kašnjenje, gubitak paketa, varijacija kašnjenja, konvergencija i kontrole količine
paketa (engl. Policing). Usporedna analiza obavljena je na temelju stvarnih podataka
prikupljenih nakon provedenih mjerenja. Rezultati istraživanja pokazuju da MPLS mreže
omogućuju veću efikasnost, bolju optimizaciju prometa i niže kašnjenje u usporedbi s
tradicionalnim IP mrežama.

Abstract (english)

In this thesis, MPLS (Multiprotocol Label Switching) technology is discussed, which today plays
a key role in packet transport networks. MPLS represents an upgrade to traditional packet
transport, making the detailed analysis of each packet by routers unnecessary. Instead, it uses
the method of label switching, where packet forwarding is simplified by adding labels. This
technology allows significant improvements in the quality of service, including high
availability, low latency, and minimal packet loss. The paper provides a detailed description
of the features, development, and architecture of MPLS networks, the protocols used for data
transport, as well as the fundamental parts of the network, and the process of determining
the next hop and forwarding packets according to classification. In the research section of the
thesis, measurements and analysis of key quality of service indicators such as throughput,
delay, packet loss, jitter, convergence, and policing were conducted. A comparative analysis
is performed based on actual data collected after the measurements were conducted. The
research results show that MPLS networks provide greater efficiency, better traffic
optimization, and lower latency compared to traditional IP networks.
